Radiation therapy is used in the management of a number of childhood cancers and can have significant effects on skeletal growth. We present the case of a 35-year-old woman who developed a hypoplastic pelvis and buttocks following radiotherapy for rhabdomyosarcoma of the vagina at the age of 2. At the age of 25, the patient underwent bilateral buttock augmentation with a two-stage reconstruction using tissue expansion followed by definitive augmentation with anatomical breast implant insertion. The patient continues to have a satisfactory outcome 10 years following reconstruction, having undergone a single uplift procedure and exchange of implants through the original incision 9 years postoperatively...

BACKGROUND: Acellular dermal matrices can be combined with implant-based breast reconstruction to help optimize outcomes. SurgiMend PRS is a fetal bovine dermis-derived acellular dermal matrix composed of type I collagen and approximately 30 percent type III collagen, sharing many of the properties of human cadaveric acellular dermal matrix. METHODS: This was a retrospective, single-center analysis of 111 adult patients (147 breasts) undergoing one-stage (83.7 percent) or two-stage (16...

PURPOSE: A growing trend in breast reconstruction has been placement of tissue expanders in the pre pectoral space. This is a change from the practice of placement under the pectoralis major with or without an acellular dermal matrix (ADM) sling. The move toward pre pectoral placement with an ADM wrap has the intent of decreasing post-operative pain and decreasing animation deformities. The cosmesis of pre pectoral reconstructions in the setting of post mastectomy radiation has also appeared improved in our early experience, when compared to submuscular reconstructions...

This report aims to propose and present an evaluation of a robust pencil beam scanning proton multi-field optimized treatment planning technique for postmastectomy radiation of breast cancer patients with implanted tissue expanders containing an internal metal port. Field-specific split targets were created for optimization to prevent spots from traveling through the metal port, while providing uniform coverage of the target with the use of a multi-field intensity modulated optimization approach. Two beam angles were strategically selected to provide complementary target coverage and plan robustness...

The objective was to determine the 10-year oncological safety of nipple-sparing mastectomy (NSM) in patients diagnosed with ductal carcinoma in situ (DCIS). The use of NSM preserves the nipple-areola complex (NAC). As residual fibroglandular breast tissue can remain behind the spared NAC, its use for patient with breast cancer is controversial. The oncologic outcomes and complication rates after performing NSM compared to other techniques are still under debate and a concern when treating patients with breast cancer...

Patients who undergo breast reconstruction experience higher complication rates if they have had a history of radiotherapy. However, implant-based reconstruction confers significantly higher complication and reconstruction failure rates compared with autologous reconstruction. This article analyses the factors that contribute to the complications of the different breast reconstruction modalities and the strategies described to mitigate these problems.

Permanent seed implantation (PSI) brachytherapy is a highly conformal form of radiation therapy but is challenged with dose inhomogeneity due to its utilization of low energy radiation sources. Gold nanoparticles (AuNP) conjugated with electron emitting radionuclides have recently been developed as a novel form of brachytherapy and can aid in homogenizing dose through physical distribution of radiolabeled AuNP when injected intratumorally (IT) in suspension. However, the distribution is unpredictable and precise placement of many injections would be difficult...

BACKGROUND: Implant-based breast reconstruction is the most common type of reconstruction after postmastectomy radiation therapy (PMRT). The impact of the timing of PMRT to a tissue expander or permanent implant is not well understood. The purpose of this systematic review was to evaluate outcomes in implant-based reconstruction and the timing of PMRT. METHODS: A review of the English literature in the PubMed/MEDLINE database (2000-2016) was performed to identify all articles on implant-based breast reconstruction and PMRT...

BACKGROUND: Capsular contracture is a devastating complication of postmastectomy implant-based breast reconstruction. Unfortunately, capsular contracture rates are drastically increased by targeted radiotherapy, a standard postmastectomy treatment. Thy1 (also called CD90) is important in myofibroblast differentiation and scar tissue formation. However, the impact of radiotherapy on Thy1 expression and the role of Thy1 in capsular contracture are unknown. METHODS: The authors analyzed Thy1 expression in primary human capsular tissue and primary fibroblast explants by real-time quantitative polymerase chain reaction, Western blotting, and immunohistochemistry...

PURPOSE: Differentiating tumor from its surrounding soft tissues is challenging for x-ray computed tomography (CT). Fluorescence molecular tomography (FMT) can directly localize the internal tumors targeted with specific fluorescent probes. A FMT system was developed and integrated onto a CT-guided irradiator to improve tumor localization for image-guided radiation. METHODS: The FMT system was aligned orthogonal to the cone-beam CT onboard our previously developed image-guided small animal arc radiation treatment system (iSMAART)...

Breast cancer is the most common malignancy diagnosed among women and represents a heterogeneous group of subtypes. Radiation therapy is a critical component of treatment for breast cancer patients. However, little is known about radiation response among these intrinsic subtypes. In previous studies, we identified a significant induction of FAS after irradiation in biologically favorable breast cancer patients and breast cancer cell lines. Here, we expanded our study and investigated radiation response in a mouse model of breast cancer...
